Outlook.com or Microsoft 365 work or school account account not syncing anymore

If your Outlook.com or Microsoft 365 work or school account account was syncing with your mobile device before and now it's not, see Fix Outlook.com email sync issues. You can learn how to remove your sync partnership and then you'll have to re-add your account.

You can also check the server status of Outlook.com for outages here. If your email is working on the computer and there is no outage, the issue might be with your email app.

Can't sync calendar and contacts after set up

If you set up your email as an IMAP or POP account, your calendars and contacts won't sync. You'll have to add them as an Exchange ActiveSync account. Also make sure that your email app has the correct permissions to access your calendar and contacts.

If your email account is working fine on a computer, the issue may be with your email app and you'll have to contact their support. For example, if you're having trouble adding an Outlook.com email account to the iOS Mail app, contact Apple Support. We recommend downloading and installing the Outlook mobile app for easy calendar and email management.
